今天使用命令mvn compile编译maven项目时提示错误信息,错误信息如下:
[ERROR] Failed to execute goal on project <project_name>: Could not resolve dependencies
for project com.xxx.xxx:<project_name>:jar:1.0.7: Failure to find com.xxx.xxx:obj-test-client:jar:1.1.1
in http://maven-nexus.xxx.com/repository/maven-public/ was cached in the local repository, resolution
will not be reattempted until the update interval of fintech has elapsed or updates are forced -> [Help 1]
问题原因 :
Maven默认会使用本地缓存的库来编译工程,对于上次下载失败的库,maven会在~/.m2/repository/<group>/<artifact>/<version>/
目录下创建xxx.lastUpdated文件,一旦这个文件存在,那么在直到下一次nexus更新之前都不会更新这个依赖库。
解决办法:
删除v~/.m2/repository/<group>/<artifact>/<version>/目录下的*.lastUpdated文件,然后再次运行mvn compile编译工程。
Jenkins构建时报错:
通过jenkins编译时报此错,我的maven安装目录/opt/maven ,解决方法如下:
发现obj-test-client-1.1.1.jar下载到本地时失败,从提示可知是本地仓库的缓存(cached)造成,于是我删除目录/opt/maven/repo/<group>/obj-test-client/1.1.1后Jenkins重新构建(或在项目目录 mvn 重新编译)即可编译成功!
注意你要确定远程仓库中存在此jar(obj-test-client-1.1.1.jar)包
